METHOD OF AND APPARATUS FOR ATTACHING COVERS TO HEELS F BOOTS AND SHOES.

Applicatio-n filed June 1, 1928, Serial No. 282,145, and in Australia August 12, 1927.

This invention relates to a method of and apparatus for attaching covers to heels of boots or'shoes whereby said covers are attachable to such heels more expeditiously and at less cost than by known methods and apparatus.

Said method consists in cutting the material of the cover to required size and shape; treating one surface of the cut cover with adhesive; treating the heel with adhesive; feed ing the cut cover with its adhesive treated face upwardly disposed in position on a slitted resilient pad; placing the adhesive treated heel in position in relation to the adhesive treated cover; and finally forcing the said heel and cover through the slitted pad, whereby the cover is made to adhere to the heel in its passage through the slitted pad. Where the cover consists of certain flexible material it may be necessary to stretch thecover beforeit is attached to the heel.

An embodiment of apparatus in accordance with the invention is illustrated in the accompanying drawings, in which Fig. 1 is a perspective view of the apparatus; Fig. 2 sectional elevation on plane 2-2, Fig.1; F ig, 3 sectional elevation on line 3'3, Fig. 2; Fig. 1 sectional plan on line 4l4c, Fig. 2; Fig. 5 perspective view of resilient pad and holder therefor; Fig. 6 perspective view illustrating the pad and-holder with cover and heel thereon; and Figs. 7 to 10 detail views illustrating the action of'the apparatus in connection with the covering of a heel.

A framing 1 is provided; this may be of any preferred design. At its head the framing 1 carries a fixed table 2 having a bracket 3'which has bearingopenings at and 12 therein for the plunger rods 5 and 11 respectively. The table 2 also has a bearing opening 45 for the rod 5. Both rods 5 and 11 are rigidly connected to each other through the bridge piece 10 and cooperating fastening nuts 16. To the bottom of the rod 11 is adapted to be firmly secured a foot 13 by means of the pinching screw d7 or otherwise; the foot 13 has a recess 48 therein to receive an end of a 'heel 14' which is to be covered and such foot 13 is also suitably shaped to suit the contour of contiguous portions'of the heel 14.

Table 2' has an opening15 therein located below the foot 13 and on the table 2 over said opening is situated a resilient pad 16 ofrubber, leather, felt or other suitable material and of appropriate thickness; such pad 16 is carried in a metal holder 17, and the latter with pad therein is adapted to be positioned on the table 2 through the guide brackets 18 which are secured'to the table 2. The pad 16 is furnished with a H-shaped slit, the connecting slit 19 joining the end parallel slits 20 and 21 respectively; the edges of the said slits are adapted 'to serve as wiper flaps for a cover-28 when a heel 14 is bein forced through the slits 19-21 in thepa 16. 1

Beneath the table 2 and depending therefrom are a pair of brackets22 each of which carries a trunnionpin 23 to each of which is pivoted a sector shaped wing 24. Each of the wings-2 1 is provided with an arm 25 to which is connected one end of the links 26 whose other end is connected to the -knucklejoint bracket 6 fixed to the foot of the rod 5. Such bracket 6 has also connected thereto one end of a jawed link 7 whose other end has attached thereto an operating foot pedal 8 which is pivoted at itsrear end tothe frame 1. An extensible coil spring 9 is attached at one end to the pedalS and at the other end to the frame 1. Secured to the brackets 22 by screws 48 or otherwise and positioned cen-- trally of the wings 24- is a chute 27.

Arms 30 may be pivoted to pins 31 fixed to the table 2; the rear end of each of the arms 30 has connected thereto one end of the respective extensible coil springs 32, the other ends of'such springs being connected to the bracket 3. Each of the pins 31 is also fitted with a compressible coil spring 33; the forward end of each of the arms 30 has pivoted thereto a foot 29 (see Fig. 1), and each of such arms 30 is also provided with a ramp 34 furnished with a hook 35 (see Fig. 3). A lever 36 is pivoted to the pins 31 and such lever has a pair of operating handles 37. The lever 36 is adapted to be engaged by a lever 38 which has a hook 49 and is pivoted to the bracket 3 the latter having a stop thereon for the lever 38. Such lever 38 is connected to one end of an extensible coil spring 30 with associated parts and lever 36 serve when in operative relation to each other to hold a-heel cover 28 cenand the feet 29 on the arms 30 contact with the trally and in stretched position over the H- slit in the pad 16, and the lever 38 serves to sustain the lever 36 with arms 30 in upraised position while the cover 28 is being placedon the pad 16. The arms 30, lever 36, and lever 38 with appurtenant parts thereof above described may be omitted when covering material 28 which does not require to be stretched is utilized for covering heels 14 on the apparatus. I I

in operation, assuming that a cover 28 has been cut to suitable shape and size and has been coated on one face with an adhesive, say rubber solution, it can then be placed on the upper surface of the pad 16 over the slits 19 21 therein with its adhesive coated surface upwardly; similarly whenaheel 14 has been coated with the adhesive on. the portions thereof to be covered it is positioned in relalion to the cover 28 with its adhesive treated portions opposite such cover. Before such positioning of the cover 28 on the pad 16, the handles 37 are elevated to enable the lever .36 to be engaged by the lever 38 whereby the lever-36 and arms 30 will be capable of elevation through operation of the lever 38 to leave the pad'16 clear to receive the cover 28. Positioning of the heel 14 in relationto the cover 28 on the pad is such that portion of the rand or heel seat 43 of the heel 14 will be located in the recess 48 of the foot 13; the breast 34 of the heel 14 will abut the lower face of the foot 13; the rand 01' heel 43 will be in alignment with the slit 20 of the pad 16; the face 42 of the heel 16 will be in alignment with the slit 21 of the pad 16; and the rear back 41 of the heel 14 will be in alignment with the connecting slit 19 ofthe pad 16. Such positioning of the cover 28 and heel 14 in relation to the pad 16 is shown in Figs. 7 and 8.

Upon'release of the lever 38 from the lever 36, the. arms 30 and such lever 36 descend,

opposite sides of the cover 28, if same is to be stretched, and hold such cover in proper position on the pad 16. When the handles 37 are forced downwardly, the lever 36 cooperating with the ramps 34 on the spring controlled arms 30, such arms are forced laterally outwards and at the same time pressure is exerted on the arms 30 and feet29 associated therewith, whereby-the cover 28 is held firmly by I such feet and is simultaneously stretched to the pedal 8 through the link 7 and knucklejoint 6 attached to the plunger rod 5. Movement of the pedal 8 downwardly ensures simultaneous downward movement of the plunger rods 5 and 11 whereby the foot 13 carrying the heel 14 to be covered will also bemoved downwardly and the heel 14and cover piece 28 will be forced through th'e'H-slit ofthe pad 16 (see Figs. 8 and 10). In passing through such slit the cover 28 will be caused to adhere to the heel 14 through contact of the edges of the said slit with the said cover. The covered heel after passing through the H-slit in the pad 16 falls into the chute 27 through which it is delivered from the apparatus.

When pressure on the pedal 8 is released the coil spring 9 will automatically cause the pedal 8 with the plunger rods 5 and 11 and foot 13 to ascend, and when the foot 13 is clearv of the pad 16 the wings 24 will operate to force the edges of the slits in the pad 16 (see Fig. 10) to normal lever position thereof (see Figs. 7 and 8) Upon raising the hand levers 37, the lever 36 and arms 30 with feet 29 (see dotted lines Fig. 2) will bev upraised and may be supportedin such position by the lever 38 automatically engaging with the lever 36 to enable next sequence of operations in heel covering to be effected.
